SPECIFICATION forming part of Letters Patent No. 523,485, dated J'uly24, 1894. Application filed October 23, 1893. Serial No. 488,869. (Nomodel.)

To au whom t may concern:

Be it known that I, GEORGE J. RECORD, a citizen of the United States,residing at Con'- neaut, in the county of Ashtabula and State of Ohio,have invented'a certain new and useful Tin-Plate Cleaning and PolishingMachine, of which the following is a full, clear, and exact description.

My invention consists of a large, hollow, rotarydrum; smaller drums andpulleys connected by chains, or their equivalent, operating within saidlarge drum; frames for supporting said drums and pulleys; a table, themeans for driving the rotatable parts and the several supplementarydevices hereinafter fully described. The large drum `is designed, whenin motion, to hold by centrifugal force a quantity of whea'shorts,commonly called bran, against the interior of the periphery of saiddrum.

The object of my invention is to provide a machine for cleaning thegrease from tin-plate and for polishingthe same.

That my invention may be seen and fully understood by those skilled inthe art, reference will be had to the following specification andannexed drawings forming a part thereof, in which-- Figure 1 is a frontview of my machine; Fig. 2, a side view; Fig. 3, afront view'of theinterior frame and the pulleys; Fig. 4, a transi verse, vertical sectionof said machine; Fig. 5, a bottom view of the small drums; Fig. 6, anenlarged view of one of theplows; Fig. 7, a top view of the cleaner forthe grooves in the drums; Fig. 8, a perspective view of the trough usedto remove the bran from the large drum; Figs. 9 and 10, front and sideviews of a chain, and Fig. 11, ,a top view of the table.

Similar gures of reference designate like parts in the drawings andspecification.

The shaft 1 has its bearings secured to the external frame 2 andsupports the internal frame 3. The large, hollow drum 4 is rigidlyattached to the shaft 1 and said shaft turns loose in the framev 3. Thedrum 4 is open ill front with the exception of the iiange 4a whichprevents the bran 5 from escaping when said drum is in motion. Thedrum4is connected', by the belt 6, with the pulley 7 on the maindriving-shaft 8.

On the rear end of the shaft 1, outside of the frame 2, is thesprocket-wheel 9 connected, by the chain 10, with the sprocket-wheel 11,on the shaft 12. The friction clutch 13 engages or disengages thesprocket-wheel 9 with or from the shaft 1. The shaft 12 is secured totheoutside of the frame 2, across one end, and has the beveled-gear 14 fastto the front end thereof. The gear 14 meshes with the gear 15 rigid onthe end of the shaft 16.y

The shaft 16 Ais attached to the front of the frame 2 and is providedwith the/two beveledgears 17 and 17.

The shafts 18 and 18, having their bearings in the frame 3 and attachedto the frame 2, support the drums 19 and 19t respectively. Fast on thefront end of `each of the shafts 18 and 18 is the gear 2O meshing withone of the gears 17 on the shaft 16. The drums 19 and 19 are providedwith the grooves 19h, as best shown in Fig. 4, in which run the endlesswire-cords 21. The cords 2l pass over the drum 22 on the shaft 23, saidshaft being journaled in the frames 2 and 3. The drum 22 is Aprovidedwith the grooves 22. The nearest points between the interior of theperiphery of the drum 4 and the peripheries of the drums 19 and 19a areseparated by a very narrow space, as shown in Fig.1, for the pur' posehereinafter explained. j

Journaled in the frame 3 and the projecting portions 2, 2a of the frame2 are the shafts 24 and 24 supporting respectively the drums 25 and 25a.Said drums 25 andp25a are provided with the grooves 25h. Bolted to theupper part of the frames 2 and 3, each side of the center, are thesupports 26 and 26 and. the pulley-boxes 27 rest upon said supports.Each box 27 has the pulley 28 pivoted therein. The endless cords 29 passover the pulleys 28, down through the grooves 25b in the drums 25 and25, around the drums 19 and 19 and through the grooves 22tin the drum22, in the manner best illustrated in Fig. 1.

The shafts 24 and 24 areprovided with the collars 24a and 24ad andset-screws for the pur-` pose of laterally adjusting said shafts and thedrums 25 and 25a thereon to give the proper direction to the cords 29.Said shafts 24 and 24 may be adjusted longitudinally by means of thescrews 30, therebyy giving the desired NITED STATES PATENT Orrioi/ IOOpitch to the plate in its passage between the drums 19 and 19 and thecords 29. The pulley-boxes 27 may also be adjusted, through the mediumof the screws 31 which extend through the sides of the U -shaped bar 32,said bar being bolted to the top of the frames 2 and 3. The supports 26,26 and the bar 32 prevent any rocking motion of the frame 3 when theshaft 1 is revolved.

The table 33 is supported, by the projections 3, 3 (Fig. 3) on the frame3, and the brackets 34, 34, above the shaft 1 and the ends of said tableare deflected downward at an angle of about thirty-ve degrees until theyjust clear the peripheries of the drums 19 and 19. The brackets 34, 34are secured to the frame 2.

The plow 35 is attached at one end to the horizontal arm of the frame 3back of the drum 25, and at the other end to the arm 2b extendingdownward from the projecting portion 2, forward of the drum 19. Theblade 35, of the plow 35, lies near the inside of the periphery of thedrum 4 and is for the purpose of breaking up the bran 5, which wouldotherwise become tightly packed in between said drum and the drum 19.Asimilar plow 36 is shown in Fig. 3, for the purpose of breaking np thebran 5 forward of the drum 19 and other plows may be employed if deemednecessary. The cleaner 37 extends from the frame 3 to the frame 2,between the drums 19 and 19, and is provided with the fingers 37 whichextend into the grooves 19b in said drums and clear said grooves of thebran 5. Other cleaners may be used in connection with the drums 22, 25and 25,

The rod 38 extends upward from the frame 3, back of the drum 25, acrossthe interior of the drum 4 with a slight downward pitch and then turnsupward to be attached to the frame 2, outside of said drum 4. The rod 38is provided with the ring 39.

The trough 40, shown in Fig. 8, has the hook 41, at one end, and thehandle 42,at the other end. When it is desired to remove the bran 5 fromthe drum 4, the hook 41 is passed through the ring 39, on the rod 38,and the trough 40 is reciprocated by hand on said rod until said bran isentirely drawn out of the revolving drum 4.

The chain 43, shown in Figs. 9 and 10, is preferable for use in place ofthe wire-cords 21 and 29. I do not wish to confine myself to the meansset forth for adjusting the drums 25 and 25 and the pulleys 2S as anyother suitable device may be utilized for that pur pOSe. i

The operation of my machine is as follows: Revolve the drum 4 in thedirection of the arrow 44, by means of the pulley 7 on the main-shaft 8and the belt 6, and throw into said drum the desired amount of bran 5.The rapid, rotary motion of the "drum 4 distributes the bran 5, bycentrifugal force, evenly around the inside of the drums periphery.

By means of the clutch 13 engage the mechanism which actuatesI the drums19 and 19 with the shaft 1. Motion is now imparted to the drums 19 and19 in the direction of the arrows 45, but since the gears 17 and 17 aresmaller than the gears 14 and 15 the speed of said drums is much lessthan the speed of the drum 4. The tinplate 46 is placed on the table 33and moved over the inclined end of said table until it is caught betweenthe drum 19 andthe chains or cords 29. The plate'46 is now carriedslowly around thedrum 19 and against the bran 5 in the rapidly revolvingdrum 4. The grooves 22, in the drum 22, are out 0f alignment with thegrooves 25b in either of the drums 25 or 25, as will be readily seen byreferring to Fig. 5, hence the cords 29 pass diagonally around the drums19 and 19, for the purpose of 4exposing the parts of the plate 46, whichhad been covered by said cords in its passage around the drum 19, to theaction of the bran 5 when the drum 19 is reached. The plate 46 moves on,guided by the cords 21 and 29, from the drum 19, over the drum 22 andaround the drum 19, when it is `thrown upon the table` 33 with one sidethoroughly cleaned and polished. The plate 46 is now turned over andcarried around the drums 19 and 19 against the bran 5 again, to cleanand polish the opposite side. The bran 5 becomes heated by theintroduction of the hot plates 46 and for that reason more readily andthoroughly removes the grease adhering "to said plates. One of the stops47 is attached, between each pair of cords 29, to the under side of thesupport 2 6, over the drums 19 and 25, to prevent any plate 46 fromfollowing the chains or cords 29 up over the pulleys 28. VlThen the bran5 becomes foul it is drawn o by means of the trough 40, as before eX.-plained, and a fresh supply introduced into the drum 4. The object ofplacing the drums 19 and 19 so that their peripheries are close to theinside of the periphery of the drum 4 is to augment the friction atthose points between the bran 5 and the tin-plate 46, whereby thecleansing process is more complete.

I do not claim the method herein described of cleaning and polishingtin-plate as I have made that the subject for aprior application.

I do not wish to confine myself to the exact means herein shown anddescribed for imparting motion to the drums 19 and 19 from the drum 4,as any suitable device may be employed for this purpose withoutdeparting from the nature of my invention. Nor do I wish to restrict mymachine to the use of bran, as a cleansing agent, since other substanceswhich are the equivalents of bran may be utilized, with equally goodresults, if desired.
